BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 421,462, dated February18, 1890. Application filed March 11, 1889. Serial No. 302,773. (Nomodel) To all whom it may concern.-

Be it known that 1, ANDREW WIoKnY, of Quincy, in the county of Adams andState of Illinois, have invented certain new and usef ul Improvements inBailing-Presses, of which the followingis a specification.

The invention consists in various improvements in What are known asreboundingplunger presses, in which the hay or other material is fed in.successive charges into a trunk or chamber and compressed therein by aplunger and the accumulated mass forced through the contracted end ofthe trunk.

In the accompanying drawings, Figure 1 is a side elevation of abaling-press having my improvements embodied therein. Fig. 2 is alongitudinal vertical section of the same on the line 00 x of Fig. 3.Fig. 3 is a top plan View of the same. Fig. at is a perspective view ofthe tucker or detaining-plate. Fig. 5 is a vertical section 011 the line01; 0c of Fig. 3. Fig. 6 is a view of a modification. Fig. 7 is asection on the line y y of Fig. 2.

Referring to the drawings, E represents the baling-chamber, providedwith atop opening to receive the charges of material, and with thehorizontal trunk E forming a continuation thereof, and contracted towardthe delivery end to assist in the compression of the material in itscourse to the point of delivery. W'ith the exception of certain detailshereinafter described, these parts are all essentially of the sameconstruction as in presses now in general use.

The baling-chamber is sustained by an underlying axle E, the ends ofwhich are cranked upward and mounted in groundwheels BB. To the underside of the baling-chamber is firmly bolted a reach-bar E which isextended forwardand connected at its extremity by a Vertical shaft D tothe front wheel-frame 0, having at its ends journals to carry theground-wheels A A. This wheel frame or axle G is constructed with anopening therethrough from front to rear to admit the operative part-s,hereinafter described.

The compression of the charges is effected, as usual, by a reciprocatingfollower or plunger F, sometimes termed a traverser, mounted in thebale-chamber. Instead of guiding this plunger in the usual manner tokeep its face properly presented to the charge, I secure it rigidly tothe forward end of a pitman f, which receives, like the pitman in commonuse, both a longitudinal and lateral motion at its opposite end. operatethis pitman either by the special mechanism hereinafter described or byany ordinary mechanism now in general use for the purpose. Beingattached rigidly to the plunger, it prevents the latter from tipping orrocking out of an operative position. It serves not only to advance andretract the plunger, but to hold it in such position that its face ispresented fairly against the charge. Owing to the lateral vibration ofthe pitman the plunger receives a slight rocking or tipping movement ina horizontal plane as it is carried forward and backward, but thistipping action is so slight that the action is not imparted thereby.

I prefer to connect the pitman to the plunger by screwing it into arigid neck P on the back of the plunger, as shown in Fig. 2; but it isto be understood that any rigid connection of an equivalent charactermay be employed.

i In order to close the feed-opening as the plunger advances, I employ,as usual, a top plate f extending forward from the upper edge of theplunger, and in order that this plate may be moved freely forward and.backward by the rocking plunger I employ a loose joint or connectionbetween them, so that the plunger may rock horizontally without swingingthe plate sidewise. The jointed connection may be of any suitableconstruction which will permit the plunger to rock in a horizontal planeindependently of the top plate. I prefer to employ the constructionshown in Figs. 2 and 7, in which 0 represents a stirrup fixed to theunder side of the top plate and passing downward around a horizontalroller or pin 0 fixed between ears 0' and 0 on the back of the plunger.The stirrup is of such size as to permit a considerable motion betweenthe plunger and the top plate, not only in a horizontal, but also in avertical direction. Springs 19 p, seated between the top plate and thetop of the plunger, hold the plate up normally to its normal position,but admit of its sinkingin the event of the hay being wedged between theplate Ipropose to and the top of the trunk, as sometimes happens. Thetop plate is sustained at its for ward end by stationary rollers f fixedto the inside of the baling-chamber.

In order that the plunger may move forward without having the top plateproject into the path of the animals employed to operate the machine, Idivide the top plate transversely between its ends and connect the partsby a hinge, as shown at f, so that the forward end may drop to the'position indicated by dotted lines in Fig. 2. When the plunger movesinward, the rollers act to lift the hinged end to its operativeposition.

In order to retain the charges as they are moved forward by the plunger,I mount in the top of the baling-chamber, at the delivery side, adetaining-plate 11, extending entirely across the same from side toside. The plate is mounted at its forward edge on horizontal journals,and is provided at the rear edge, as shown in Fig. 4, with teeth 1; atthe delivery edge to engage the hay. The journals of the plate areprovided at their outer ends with crank-arms 12 W3, connected,respectively, to rods o '0 provided with nuts 1: and c acted upon byspiral springs of 12 The springs are mounted upon the rods and bear atthe upper ends against stationary plates '0 on the outside of thebaling-chamber. This arrangement of the parts permits the toothed edgeof the detaining-plate to rise under the pressure of the advancingcharges, but causes it to sink securely into engagement with the same.By tightening the nuts upon the rod the tension of the spring and theconsequent pressure of the plate may be increased.

In order to assist in sustaining the pitman and to relieve its operatingparts of friction, I support it upon a grooved roller Y, mounted to turnand to slide freely on a horizontal shaft y, fixed across the forwardend of the baling-chamber. The roller shifting laterally with the pitmanaffords a constant rolling support therefor.

Inorder to arrest the rebounding motion of the piston with an easyaction, I provide an adjustable stop consisting of the two timbers O andO, mounted transversely in the forward end of the trunk in position toembrace the hub P of the plunger as the latter retreats. The proximatefaces of these timbers are beveled outward, as shown, so that the hubenters between them with a wedging action. The upper timber may be fixedin position, but the lower timber O is sustained at its ends by two rods25 t, carried through L the top of the trunk and provided with adjusting-nuts s s, by means of which the lower timber maybe raised towardits companion in order to increase the frictional effect upon the hub ofthe plunger.

For the purpose of advancing the plunger and allowing the same torebound, and this by a continuous rotary motion of an operating-sweep, Iemploy the mechanism shown in Figs. 1, 2, 3, and 5. The sweep H isbolted to a plate formed upon or secured to the upper end of a verticalshaft D, so that as the sweep revolves it imparts a rotary motion tosaid shaft. The shaft carries a rigid crossarm h h, bearing at its endsthe depending studs or rollers 77. and 713. An eccentric toothed gear orrack-segment I is mounted to turn loosely around the shaft E, and is provided with an angular dog 70, connected thereto by a horizontal pivot.One end of this dog extends upward through the opening 70' in the gearIinto the path of the studs 72, 77. which are carried in a circular pathby the rotation of the sweep. The lower end k of the dog 70 is carriedby the vibration of the gear I against a stationary cam-plate Z,

fixed to the frame.

The plunger-operating pitman is provided on its side with teeth 2' toengage the teeth of the gear I, and the teeth of the two parts are heldin constant engagement by rollers i mounted on the pitman and travelingagainst the edges of the eccentrically-curved rails m m. WVhen theplunger is retracted, the parts stand normally in the position shown inFig. 3, the teeth at the outer end of the gear I being inengagement-with the pitman. As the sweep revolves, one or the other ofits studs 7% 7L3 will encounter the upper end 70 of the dog 70, andthrough the dog will cause the gear I to turn forward with the sweep. Asit turns forward, its teeth advance the pitman and plunger, the leveragegradually increasing as the teeth nearer the center are broughtsuccessively into action.. As the plunger completes its forwardmovement, the lower end k of the dog 70 encounters the cam Z, whichthrows its upper end out of engagement with the stud on the driving-arm.Although both the sweep and the drivingarm continue their rotation, thegear I and the pit-man are permitted to move backward under thereactionary pressure or effect of the charge upon the plunger. Duringthe same revolution of the sweep the second stud is brought into actionon the dog and the plunger advances, as before. Thus it is that by acontinuous rotation of the sweep the plunger is advanced and released,and this twice during each rotation of the sweep. The cam-plate Z isfixed to the frame by bolts passing through slots therein, as shown inFigs. 1 and 2, so that it may be adjusted to trip the dog sooner orlater. In this manner the point to which the plunger is advanced may bevaried at will.

In order to strengthen the structure and resist the tendency of theplunger to force the baling-chamber away from the operating mechanism, Iemploy a tie-rod M, connected at one end to the cross-bar O of thebalingchamber and at the opposite end to a lug N on the axle-frame.

Having thus described my invention, what I claim is 1. In combinationwith the bale-chamber and the reciprocating top plate therein, thereciprocating plunger jointed to the top plate to rock independently ina horizontal plane.

2. The bale-chamber and the rocking reciprocating plunger, incombination with the top plate, the stirrup connecting the plate andplunger, and the intermediate spring, whereby the plate is permitted anindependent rising-and-falling motion and the plunger allowed to rockWithout causing the plate to bind at its edges against the side of thechamber. 7

3. In combination with the baling-chamber, the plunger and thelongitudinally and laterally movable pitman fixed to the plunger, thepitman-sustainin g roller, and the shaft, whereon the roller is free toturn and slide.

4. The combination, with the laterallyand longitudinally moving pitmanhaving the plunger attached, of the grooved pitman-sustaining rollermounted to move laterally with the pitman, substantially as describedand shown.

5. The baling-chamber, the detaining-plate extending across the same andprovided with supportingjournals at one edge and with teeth at theother, in combination with the crank-arms applied to its journals, andthe rods and springs for actuating said crankarms;
